"There is supposed to be a little movement." The repairs, which consist of filling the "very minute" gaps between the base and foundation with a type of epoxy, are being done under warranty by the supplier.
Faith said it takes three days for the repairs to be completed

There are problems with the foundations of at least five of the 22 wind turbines installed this past summer at Nova Scotia Power's wind farm on Nuttby Mountain, north of Truro, CBC News has learned.
Three of the turbines are shut down for repairs because the 400-tonne concrete pads were improperly installed.

Wind turbine blade falls off again at Elkton-Pigeon- Bay Port

Smith said brief power outages experienced in the area cause the three turbines to instantly stop and recoil, which fatigues the blades in the area where they are likely to break. When the blades are new, they're more flexible and durable. ...we are going to direct all maintenance employees to approach away from the blades and keep visitors away. The blade ejection happens rarely, but we need to err on the side of safety.

This was the second time in two years the school district had a wind turbine fail due to a problem with blades. The turbine that failed this week was not the one that had earlier problems, officials said.
"At this point we're going to take a step back, find out what happened and make decisions from there," Perkins school Superintendent Jim Gunner said.
For the second time in two years, Perkins Schools officials shut down the wind turbines on school property after a mechanical failure.

By the time construction ceased, 25 of the 37 turbines slated to dot the Fairfield and Norway landscape were fully constructed.
On Friday, the company formally announced that construction had commenced again on turbines where tests were completed and foundations meet or exceed the company's standards.

The turbine never worked properly ...Enertech responded by saying the arena had inadequate amperage service, so the arena spent $23,000 to upgrade the service.
In September 2010, the turbine malfunctioned and flung oil or something similar to it over the arena.

"I had several calls from concerned residents who saw the fire, which burned for over two hours," said local county councillor Paul Marfleet.
"I went up to the site and the police and fire service were there, but there was little they could do to tackle a fire 75 metres above the ground and I did sympathise.
The problem seems to be a relay switch which has been repeatedly switching off for reasons unknown, said Mr. Crosby who has overseen the town's wind turbine project. ...The situation is complicated by the bankruptcy earlier this year of AAER, the Canadian firm that supplied the wind turbine to Portsmouth and provided the warranty protection.

The turbine sustained damage when it was struck by lightning in May. Initial inspections revealed a split on the outer tip of one blade that was less than 24 inches long. The split was repaired by LES and Vestas (the turbine's manufacturer with which LES has a service agreement) at an estimated cost of $45,000.

A six to seven metre portion came off the blade in the incident in Lem, Western Jutland, a Vestas spokesman says. He adds that the company is investigating the cause of the incident.
"We don't see this as a design fault," he says.
Hobart people are being used as guinea pigs in an experiment to test untried wind turbines, Hobart City Council aldermen said last night.
They expressed fury at the failure and damage to the turbines on Hobart's waterfront Marine Board building on August 11, coming after the council had included safety concerns in its opposition to the turbines.

They were designed to withstand cyclones but yesterday's blustery conditions were enough to wreck two wind power turbines on top of the Marine Board Building.
The turbines were seen spinning out of control in winds of up to 54km/h just before midday - before two blades came loose and fell in on themselves.
